Answer:
Each three-digit area code may contain up to 7,919,900 unique phone numbers:
NXX may begin only with the digits [2–9], providing a base of 8 million numbers: ( 8 x 100 x 10000 ) .
However, the last two digits of NXX cannot both be 1, to avoid confusion with the N11 codes (subtract 80,000).
Despite the widespread usage of NXX "555" for fictional telephone numbers — see 555 (telephone number) — today, the only such numbers specifically reserved for fictional use are "555-0100" through "555-0199", with the remaining "555" numbers released for actual assignment as information numbers (subtract 100).
In individual geographic area codes, several other NXX prefixes are generally not assigned: the home area code(s), adjacent domestic area codes and overlays, area codes reserved for future relief nearby, industry testing codes (generally NXX 958 and 959) and special service codes (such as NXX 950 and 976). Subtract for 911 411etc emergency and informational numbers

There are total 8 X 10⁹ possible 10 digit phone numbers whose first digit cannot be 0 and 1.
What is Permutation?A permutation of a set is, loosely speaking, an arrangement of its members into a sequence or linear order, or if the set is already ordered, a rearrangement of its elements.
Here, well the first digit is not allowed to be 0 or 1 so 8 (2 to 9) remain to choose.
For the reminding 8 numbers you can make any choice from 00000000 to 99999999 when you count them these are 10⁹ possibilities and when you consider the 8 possibilities you have for the first number there are 8X10⁹ possibilities total.
Thus, there are total 8 X 10⁹ possible 10 digit phone numbers whose first digit cannot be 0 and 1.

Determine the length of side BA using the Pythagorean Theorem and round your answer to the nearest tenth's place.
Answer:
2.3 cmStep-by-step explanation:
BA² = AC² - BC²BA = √AC² - BC²BA = √4.7² - 4.1² = √5.28 = 2.3 cm (rounded)Answer:
Let the required side (=BA) be x meter
According to the problem, (using the Pythagorus Theorem)
[tex] {x}^{2} + ({4.1)}^{2} = {(4.7)}^{2} \\ {x}^{2} = {(4.7)}^{2} - {(4.1)}^{2} \\ {x}^{2} = (4.7 + 4.1)(4.7 - 4.1) \\ {x}^{2} = 8.8 \times 0.6 \\ {x}^{2} = 5.28 \\ x = \sqrt{5.28} \\ \boxed{x = 2.3 \: meter}[/tex]

C. A different class is made up of 68% women and has 19 women in it. What is the total number of students in the class?
Answer:
a. 44.19%
b. 127
c. 28
Step-by-step explanation:
Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)
The required answers are-
a. The percentage of male in the class is 44.18%.
b . There are 127 men in the class.
c. Total number of students in the class are 28.
What is percentage?A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.
a. The percentage of male in the class :
Now its given that,
Number of males = 19
Number of females = 24
Total students = 43
Percentage of males = Number of males/Total students *100%
⇒ Percentage of males = 19/43 *100%
⇒ Percentage of males = 44.18%
So,The percentage of male in the class is 44.18%
b . men in the class
It is given that,
Total students = 259
Percentage of males = 49%
Number of males in the class = 49% of 259
⇒ Number of males in the class = 49/100 *259
⇒ Number of males in the class = 126.91 ≈127
So,There are 127 men in the class.
c. Total number of students in the class
It is given that,
Percentage of women = 68%
Number of women = 19
Let x be the number of women in the class.
So,
68% of x = 19
⇒ 0.68x = 19
⇒ x = 19/0.68
⇒ x = 27.94
⇒ x ≈ 28
Hence,Total number of students in the class is 28
Thus, the required answers are-
a. The percentage of male in the class is 44.18%.
b . There are 127 men in the class.
c. Total number of students in the class are 28.
